This invention relates to window assemblies and more particularly to detention windows used in connection with penal institutions and other places where it may be desirable to prevent the egress of human bodies or foreign articles through the window.

An object of this invention is to secure strength and at the same timecamoufiage so as to eliminate the objectionable appearance caused by closures mounted on the outside of windows having duo-functional muntin and detention bars.

Another object of the invention is to provide a plurality of sections independent of one another as far as the parallel muntin bars are concerned but interlocked and camouflaged.

Another object of the invention is to provide additional detention bars across the more vulnerable area of the window and more particularly across the ventilating area which may be provided with an adjustable closure arranged to protect at least a portion thereof.

Another object of the invention is to provide ventilating areas of different sizes some of which are larger than others so as toprovide ventilation commensurate with the demands.

Another object of the invention is to provide a plurality of closures one for each ventilating area, at least one of said closures being hingedly attached and another pivotally attached.

Another object of the invention is to provide a ventilating area having an adjustable closure extending across the entire window. and so arranged with respect to the wall that it deters tampering with the operators.

Another object of the invention is to provide a closure for a ventilating area that is of less depth than the window assembly but substantially flush with the outer surface of the window.

Another object of the invention is to provide screens for the ventilating areas some of which are located on the outside and others on the inside.

Another object of the invention is to provide a screen that is snapped in position.

Another object of the invention is to provide a window assembly that is cheap in construction, easily assembled, efficient in operation, and that affords adequate protection.

Another object of this invention is to provide a plurality of ventilating areas having adjustable closures oppositely disposed, some of the closures being located on the inside and others on the outside.

When duo-functional detention bars are used as disclosed in co-pending applications to Lee Bayley, Serial No. 431,117 filed February 25, 1930 now Patent No. 1,948,159 granted February 20, 1934, and Serial No. 496,709 filed November 19,

1930 now Patent No. 1,948,160 granted February 20, 1934, application to William Bayley Serial No. 588,155 filed January 22, 1932 now Patent No. 1,948,230 granted February 20, 1934, and applications to Zimmerman'SeriaI No. 469,969 filed July 23,1930 now Patent No. 1,948,152 granted February 20, 1934 and Serial No. 507,789 filed January 10, 1931, now Patent No. 1,948,153 granted February 20, 1934, all assigned to the William Bayley Company, it has been found that the closures mounted on the outside or on the inside of the window present an objectionable appearance, the closures being extremely conspicuous. In the modification disclosed in this application the closures have been built into acamoufiaged assembly wherein the closure although located on the outside or inside as the case may be is not so conspicuous as a false frame work has been incorporated into the structure so as to make the closure appear as though it is a portion of the window proper rather than an addition thereto. In the above referred to copending applications there have been one and in some cases two closures disclosed but where two closures have been disclosed they have been shown of equal size and on the same side of the window. It is very desirable in some constructions to have the closures of different sizes and one opening inwardly and the other outwardly so as to secure the proper ventilation without jeopardizing the security of the window assembly.

Referring to the drawings, like reference characters have been used to indicate like parts throughout the several figures.

The reference character 28 indicates a plurality of transversely arranged muntin bars dividing the window into a plurality of spaces some of which are glazed and others at 22 and 24 unglazed forming ventilating areas. In addition to the transversely arranged muntin bars 28 a plurality of muntin bars 26 also transversely arranged form an independent section adjacent to the main section but tied thereto by a vertical U-shaped member 28 having one leg contacting the muntin bar 28 and the other the muntin bar 26. The webs of the muntin bars 28 and 26 are spanned by a projecting member 38 which leaves a void 32 forming a dead air space. Member 28, as best seen in Fig. 3, projects inwardly from the window proper and is substantially flush with the inner face of the closure 34. Referring to Fig. 2 the upper cross piece 36 and the sill 38 have extensions 40 extending into the U-shaped members 28 so that the inner faces of the U- shaped members 28, members 36, 38 and 40, are substantially in one plane, thereby presenting a camouflaged appearance as though the closure is within the body of the window assembly. The sill 38 may be inserted after the window is assembled as the horizontal muntin bars passing through the ventilating area are undercut at 42 which received the hooked edge or lip of the sill 38. The hooked edge of the sill 38 overlaps the inner flange of the muntin bar so as to form a suitable water shed.

In the modification disclosed inFig. 2 the lower ventilating area is protected by a screen 44 carried by a frame 46 provided with grooves or notches 48 in which are seated the hooks 58 welded to the transverse muntin bars 29 and the removable hooks 52 located to engage the groove on the opposite side of the frame and held in position by the screws 54 provided with a special head of which no two sides are parallel, as disclosed in Fig. 6. In this particular modification a pentagon head has been used. The screen 44 prevents or deters the cutting of these bars bounding the lower ventilating area disclosed in Fig. 1. The screen 44 hinders the inmates on the inside from removing or tampering with the putty holding in position the window panes in the glazed areas.

The closure 60 for the ventilating area 22 is pivoted at 62 so that the upper portion of the closure swings inwardly and the lower portion outwardly. The swinging movement of the closure 60 is limited by a suitable chain 64 and the lower portion of the closure is guided by guide member 66 carried by the muntin bars 28.

In order to deter the cutting of the muntin bars bounding this ventilating area which is not screened, the muntin bars 20 are provided with reinforcing members 88 preferably of hard and tool proof material which prevents the cutting of the muntin bars 28. Likewise the upper portion of the closure 60 is provided with a rein- 5 forcing member ID also of tool proof material to prevent the inmate from cutting the closure.

The lower spaces of the window in the modification disclosed in Figs. 1 and 2 have been paneled by sheet metal panels 72. If desirable these 10 could be glazed.

Referring to the modification disclosed in Fig.

5 the closure is provided with a window pane 82 substantially flush, with the window panes 84 in the main portion of the window. The window 5 pane 82 is held in position by channel-shaped members 88 integral with members 90 or suitably attached thereto. Members 98 are carried by a rectangular frame 86 that is pivotally mounted upon the closure frame surrounding the ven- 20 tilating area. Removal of screws 92 permits the removal of members 88 and 90 from the frame 86. The vertical and horizontal portions of members 88 and 90 may be separated to permit the removal and replacement of the window pane 82. 25

In this modification the screen 94 is mounted upon a frame 96 one side of which is provided with studs 98 projecting into suitable apertures in the muntin bars 28 on one side of the ventilating area. The opposite side of the frame 30 is provided with eyes I00 receiving the screws 54 for holding the opposite edge of the screen frame in position. The screw 54 is preferably provided with a pentagonal head so as to have no two sides parallel which deters its removal. 35

Referring to the modification disclosed in Figs.

7, 8, 9 and 10 the lower closure I I2 extends from wall to wall across the entire window so that the wall of the building provides an obstruction hindering the tampering with the closure operators. 40 This is especially desirable for the lower closure which is oftentimes quite accessible to the inmate. When this closure is pivoted at 4 l4 so as to open inwardly from the top it can be readily seen that if the inmate cannot tamper with the operators 45 the closure will form an obstruction hindering the cutting of the transverse muntin bars 20. With the closure in position the inmate must assume an awkward position when cutting the muntin bars. 50

A screen H6 has been mounted outside the ventilating area. The closure H8 for the upper ventilating area when closed does not project from the outside plane of the window but is inset so as to be substantially flush with the 55 window. In this modification the screen I28 has been located on the inside of the upper ventilating area so as to prevent the inmate from cutting or reaching the transversely arranged muntin bars I22 which have been reduced in depth to 0 accommodate the closure H8. A suitable water shed I24 overhangs the upper portion of the closure to prevent rain from coming in along the upper edge of the closure. The window pane in this modification is held in place by members 83 5 similar to the disclosure in Fig. 5.

In the modification disclosed in Figs. 11 and 19 the closure 538 is pivotally mounted at I32 which pivot is located nearer the bottom of the ventilating area than the top. Then the clo- 7 sure is open as disclosed in dot-dash position the lower portion of the closure frame E34 is so located as to prevent the ready escape of the inmate through the lower half of the ventilating area. In order to prevent the escape of an inmate 7 through the upper portion of the ventilating area which may be referred to as the more vulnerable portion, detention bars I36 terminating at I38 and forming a detention grill extend across the ventilating area above the pivot I 32. Thus the more vulnerable portion of the ventilating area is provided with additional protection which deters the escape of inmates. This modification is very well suited for semi-detention work such as in sane asylums, hospitals, orphanages, and for that matter private homes, apartments and hotels.

In the modification disclosed in Figs. 11 and 19, the pivot of the closure is located below the center of the window. The pivot could be located above the center of the window or at the center of the window, in which event a grill like !36 could be inserted inside and below the pivot. Thus if the closure is pivoted at the center there would be one grill on the outside and one grill on the inside. If the pivot is sufiiciently high to prevent the escape of an inmate between the closure and the top of the Window, a grill located on the inside covering the space below the pivot would be suflicient. The closure disclosed in Figs. 11 and 19 may be mounted in an offset frame bounding the ventilating area, similar to the frame disclosed in Fig. 8. If this is done a grill I36 may be used to protect the more vulnerable area if the muntin bars do not extend across the ventilating area. If the muntin bars do extend across the ventilating area it would be necessary to out some of the muntin bars so as to permit the lower portion of the closure to have a swinging movement into the plane of the muntin bars.

Referring to Figs. 12 and 13, detention windows of other than rectangular form have been shown that are also provided with a camouflage so as to eliminate the objectionable appearance of a closure mounted within the window. In these modifications the closure 566 is mounted inside of the muntin bars 26 but the remainder of the window has been provided with a false work I52 as disclosed in Fig. 14, the transverse muntin bars 20 carrying members I54, shown in Fig. 16, that increases the apparent depth of the muntin bars. The inner plane of members I52 and IE4 are substantially flush with the inner plane of the closure I56 and its frame I56.

In the modification disclosed in Fig. 14 the screen I60 is provided with a grooved frame I64 which receives the hooks I 66 carried by the muntin bar bounding one side of the ventilating area. The opposite side of the frame I 64 is provided with a beveled groove that receives the hook I68 beveled at I and carried by muntin bar 26 supported by the screws 54. The hooks I66 are of resilient material so the screen frame I64 may be snapped into position without the removal of the screws 64 but cannot very well be removed unless a special tool is provided therefor I or the screws 54 removed.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its adbe understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of itsforms or modifications within the legitimate and valid scope of the appended claims.
